SEMIANALYTIC DISTRIBUTIONS IN FOUR FERMION NEUTRAL CURRENT PROCESSES
Arnd Leike
Abstract
Analytical formulae for triple differential distributions d3σ/( dθ ds1 ds2) in the neutral current process e+e-→ f1 f1 f2 f2 are given. They allow to obtain angular distributions, rapidity distributions and transversal momentum distributions of one fermion pair by only two numerical integrations. Cuts can be applied to the integration variables.
